Technical description of the burner
Electrical connection of flame sensor
It is important for signal transmission to be almost totally free
of any disturbances or loss:
•
always separate the detector cables from the other cables:
– Line capacitance reduces the magnitude of the flame signal.
– Use a separate cable.
• Respect the allowed cable lengths.
